Overview
Nickel acetate tetrahydrate (CAS 6018-89-9 ) is a water-soluble nickel salt used as a catalyst precursor and surface treatment agent across several industrial sectors. It delivers controlled nickel ion release in solution.
This chemical is suitable for processes where precise metal deposition or activation is required. In textile and leather finishing, it functions as a mordant and fixative, improving dye uptake and wash fastness on treated substrates.
Electroplating and anodizing operations use it as a sealing agent for anodized aluminum, closing surface pores to enhance corrosion resistance. This ensures long-term durability for metal components in harsh environments.
As a catalyst precursor in polymer and specialty chemical synthesis, it is calcined or reduced to generate active nickel species. These species are essential for hydrogenation and related chemical reactions in manufacturing.
In pharmaceutical manufacturing, it serves as a reagent and process chemical where nickel-mediated catalysis is required at laboratory or pilot scale. Its consistent performance makes it a reliable choice for R&D.
Nickel acetate tetrahydrate is supplied as a green crystalline solid or powder. It is available in technical and reagent grades, with purity specifications typically ranging from 98% to 99%+ depending on the application.
Packaging options generally range from small laboratory quantities to bulk industrial supply. This flexibility allows manufacturers to source the exact volume needed for their specific production or research requirements.
